Subsea7 announced the award of a supermajor contract by Petrobras, following a competitive tender, for the development of the Sépia 2 field located approximately 280 kilometers southeast of Rio de Janeiro, Brazil, at a water depth of 2,170 meters in the pre-salt Santos Basin. Sépia 2 is one of the largest pre‑salt expansion phases, playing a central role in Brazil’s energy development.

The contract scope includes engineering, procurement, fabrication, installation, and pre-commissioning of subsea umbilicals, risers, and flowlines (SURF) for 17 wells, including two wells from the Sépia 1 project, and one gas export line with 18 risers.

Project management and engineering will commence immediately at Subsea7’s offices in Rio de Janeiro, Paris, and Sutton, with offshore operations scheduled to be executed from 2029.

Yann Cottart, Senior Vice-President Brazil and Global Projects Center West, said: “This award strengthens Subsea7’s portfolio of projects in Brazil and reinforces our established relationship with Petrobras in the pre-salt. Through strong local content, disciplined execution, and close collaboration, we support projects of national importance with predictable delivery. We thank Petrobras for their continued trust and look forward to the successful delivery of the Sépia 2 project.”

Subsea7 defines a supermajor contract as being over $1.25 billion.
